It's not under the sand. Surveyors have been measuring like this for years. I was actually surprised it took track this long to catch up. You can see them holding up the stick that catches the laser from the board. You can find the equipment for a couple grand on any site like mf.

Anyone know how this works?

So the question:
For trigonometry to work the third non-stationary point has to be accurately identified. How is that done? Saying "they do it by laser" is not explicit enough for this crowd.

1.) Congratulations Brittney! Her accomplishments often go relatively underpublicized.
2.) It alarms me that the measuring is being done this way. I feel like results can easily be manipulated or mis-recorded. Just wait for the long jump scandal where somebody jumps 8.96m, but computer sensors record it as 8.66m, and it's never ratified as a WR.

The system, which made its World Championship debut four years ago in Daegu, uses stereophonic cameras to capture the landing area for the long and triple jumps, which are calibrated in advance of the event. For each attempt, images are created and used to identify the precise landing point in the sand.

I think it is time to do away with the long jump board altogether. Now with lasers and such, they can just measure the true distance of the jump from start to finish. Just have a one meter area that the jumper has to take off from. Getting rid of all those fouls would make the sport more exciting.
